Ancient Groom Returns

An ancient ancestor of a powerful family is over 800 years old and has lived since medieval times. He resides on a mountain with his great-grandchildren, all in their late 80s or 90s. When a disaster is predicted, he is forced to come down the mountain and marry the world's most beautiful woman. The family descendants have never seen him, so when they meet him, they mistake him for a scam artist. His bride-to-be also thinks he is an impostor, leading to a chaotic reunion where ancient power meets modern doubt.
